Include fixing bolt, plain washer and spring washer, fixing bolt sequentially passes through spring washer, plain washer, cover plate for manhole and manhole method
Orchid, cover plate for manhole and manhole flange are fixed together, and described cover plate for manhole is provided with handle.
Further, the quantity of described fixation kit is multiple, and the plurality of fixation kit is in all along the circumference of cover plate for manhole
Even distribution.
The beneficial effects of the utility model are：Manhole flange, manhole method are welded with the fuel tank tank wall in this utility model
It is covered with cover plate for manhole, cover plate for manhole is connected by fixation kit with manhole flange, thus making in transformator or overhauling on orchid
When, fixing bolt can be backed out, open cover plate for manhole, staff can pass in and out the fuel tank of transformator by manhole flange, or
Person using probe enter transformator fuel tank, to observe the inner case of the fuel tank of transformator, facilitate implementation transformator make or
Maintenance.Structure of the present utility model eliminates the pipe of one section of lengthening, more convenient people's turnover, reduces processing cost, facilitates
Operation, improves production efficiency, optimizes the function of manhole.In addition, manhole flange is arranged at fuel tank by way of welding
On tank wall, so that inlet manhole is closer to fuel tank, convenient staff's turnover.Cover plate for manhole and manhole flange it
Between be provided with sealing gasket so that it is ensured that the sealing state of manhole when transformator normally runs.There is in fixation kit spring pad
Circle and plain washer, by the cooperation of spring washer, plain washer and fixing bolt, so that between cover plate for manhole and manhole flange
Be fixedly connected more reliable.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of cover plate for manhole.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
As depicted in figs. 1 and 2, a kind of manhole device of 110kV power transformer, including manhole flange 1, cover plate for manhole 2
